[0007] When extracting sewage, hold the handle with one hand and push the limiting sleeve into the sewage. When it reaches the appropriate position in the sewage, rotate the knob with the other hand to make the water inlet pointer point in a symmetrical direction, so that the second water inlet of the sewage extraction cylinder is connected to the first water inlet, and the sewage can enter the sewage extraction cylinder through the first water inlet and the second water inlet. Then rotate the knob again to return the water inlet pointer to its original position, thereby completing the sewage sampling work.

[0008] Preferably, there are five first water inlets in total, and the five first water inlets are evenly and equidistantly distributed about the limiting sleeve.

[0009] Preferably, the sewage extraction cylinder is a sealed circular cylindrical container, and there are five sewage extraction cylinders in total. A second water inlet is opened at the upper position of the side end surface of the sewage extraction cylinder, and the second water inlet corresponds to the position of the first water inlet.

[0010] Preferably, a second magnet block is installed at the lower end of the mounting rod, and the second magnet block is inserted and adsorbed in a positioning groove of the sewage extraction cylinder located above.
